Its unique four ceramic-element construction produces an elliptical beam that covers a wider area and produces excellent target resolution. The combination of 50 and 200 kHz make it a great option for both shallow and deep-water use. The included High-performance Fairing gives excellent results at speeds up to 30 knots (34 MPH).\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eAcoustic
